The geotextile vertical permeability tester is a horizontal constant head tester designed and manufactured according to the latest national standard GB/T15789-2005 and the requirements of the "Test Code for Geosynthetics in Highway Engineering JTG E50-2006" newly issued by the Ministry of Transport. It is suitable for testing the vertical permeability of various geotextiles and composite geotextiles with permeability under constant head. The national computer software copyright certificate number of this machine's geosynthetics vertical permeability tester is Software Copyright Certificate No. 2452896.

GB/T15789-2005 Method A JTG E50-2006 T114-2006 Vertical Performance Test (Constant Head Method)

Flow velocity of water flowing perpendicular to the plane of geotextile under unit hydraulic gradient (mm/s)

1. This machine adopts a 7.8-inch high-definition touch color screen system and a Chinese menu operation interface.

2. The testing fixture is made of high-quality aluminum alloy material, which is corrosion-resistant, easy to clean, and aesthetically pleasing.

3. Having the copyright certificate of geosynthetic material vertical permeameter software and a valid software qualification inspection and testing report issued by a national inspection and testing institution, with the "CMA" mark on the testing report.

4. Adopting a fully transparent organic glass testing chamber, the testing process is intuitive and clear.

5. Using DuPont powder from the United States and electrostatic spray painting process, it solidifies at a high temperature of 200 ℃ without fading.

6. Sample clamping method: horizontal water flow, sample loading in water, sample clamping with force rod.

7. The permeable water collection volume is measured using a graduated cylinder and displayed on high-definition scales.

8. The whole machine has no exposed plastic hoses and adopts a zero pipe experimental chamber to effectively prevent the generation of bubbles and ensure accurate data.
